Abstract

  We reported the efficacy of training for a patient who was considered to have phonological dyslexia. The participant was a 63-year-old male and was right-handed. He showed pseudohomophone effects and several lexicalization errors on non-word reading. Simultaneously, he presented phonological deficits and experienced difficulty in sequential information processing. The training program was consisted of the following: (ⅰ) phonological extraction (extracting the first syllable of a word that was spoken) and phonological blending (blending the last syllables of two words that were spoken) , (ⅱ) phonological blending (blending three syllables of non-words that were spoken one syllable at a time and then quickly repeating the integrated syllables, and (ⅲ) sequential movement of hand shapes (performing a hand action as directed) .The patient was not trained to read aloud while this program was carried out. After three weeks of training, the patientʼs performance in phonological extraction, phonological blending, and sequential movement of hand shapes improved. In addition, the number of non-words that were correctly read significantly increased. However, the patient continued to experience slight difficulty in grapheme-phoneme conversion.His inefficiency in reading non-words might be attributable to his phonological deficit and impaired sequential processing.
